Thermal cutouts promise best of both
worlds
Pepi's JS series thermal cutouts combine the benefits of both automatic and manual reset cutouts, without the disadvantages of either.

Thermal sensor features faster response
When Semitec came to develop a new surface-mount ring terminal sensor using its latest AP series NTC thermistor, it wanted to improve on a couple of aspects of the existing all-plastic design.
During normal operation, the load current flows through the contacts of the Pepi JS as with any typical thermal cutout.
When the temperature set-point is reached, the contacts snap open and the current then flows through the model JS's internal resistor.
The resistor then self-heats and provides sufficient heat to stop the contacts from auto-resetting.
The Pepi JS can only be reset by switching off the applied voltage and then waiting until it has sufficiently cooled down.
Despite its compact sise, the Pepi JS is capable of switching loads up to 13A/250V AC and is approved by UL and VDE to IEC60-730.
It is available in both 230 and 120V versions and is ideal for applications where an auto-resetting cutout is either undesirable or considered dangerous.
